FLOWER-POT.

SPECIFICATION forming part of Letters Patent No. 650,614, dated May 29,1900. Application filed February 21, 1899. Serial No. 706,403. (Nomodel.)

To all whom, it may concern.-

Be it known that I, ALEXANDER RoEsELER, a subject of the King ofPrussia, German Emperor, residing at Franzosirchestrasse 17, Berlin, W.,Prussia, German Empire, have invented certain new and usefulImprovements in Flower Pots and Vases, of which the following is aspecification.

The present invention relates to flower pots and vases and the like; andit consists in providin g these receptacles with double walls inclosinga stagnant layer of air and in providing the bottoms of the same withinwardly and upwardly extending tubes or pipes instead of the ordinaryorifices hitherto employed.

In order to render the present specification more easilyintelligible,reference is had to the accompanying drawings, in which similar lettersof reference denote similar parts throughout both views.

Figure 1 is a vertical section through the pot, and Fig. 2 is a planview of the same.

The pot or vase is provided with double walls a and I), closed at thetop by an annular ring 0 and open at the bottom, which closes up theinner wall only. The pot itself is provided with feet 6 e c, any desirednumber of which may be employed, and inwardly-extending tubes f f arearranged in the said bottom (1, so that all the water fed to thecontents of the pot will not at once escape, as is the case with theordinary flowerpots; but a certain quantity will remain, which may thenbe absorbed by the earth in case the flower or other plant in the potmay at any time not have been watered by inadvertence or from any othercause. The tubes f f constitute overflow-pipes.

The eifect produced by the double-walled pot is that the roots of theplants therein will not be subjected to sudden changes of temperature,because the stagnant layer of air within the walls constitutes a badconductor of heat, and thus compensates sudden temperature changes.

In the present invention particular importance is attached to the factthat no air circulation is possible between the walls, owing to thespace being closed at the top, because it' this were not the case theair-cushion would always have approximately the same temperature as theouter air, and the roots of the plant would not be protected in themanner above described-i. e., changes of temperature without would notbe compensated by the stagnant layer of air between the walls.

The material of which the pots or vases are constructed may be of anydesired kind.

By means of the pipes f f air will be able to pass upwardly into theearth contained in the pot and the said earth may from time to time bepierced by a needle or pointed instrument inserted through the tubes ff,so as to loosen it. The water fed to the plant will not run out at thebottom entirely, as has been hitherto the case, but a certain supplywill remain in the pot, which will be absorbed by the earth whennecessary.

I claim as my invention- A flower-pot having double walls a,b, joined atthe top and open at the bottom to inclose a layer ofstagnant air and aseries of inwardly-extending overflow-pipes farranged in the bottom ofthe pot, substantially as described.

Signed at Berlin, Germany, this 7th day of February, 1899.
